It's like the same thing for adding. For example if you have 3 x 4. You can add 3 four times or you can add 4 three times. Like this.
3 + 3 + 3 + 3 = 12 because you know 3 + 3 =6 and 6 + 6 equals 12.
OR
4 + 4 + 4 = 12 because you know 4 + 4 = 8 and 8 + 4 equals 12.

y + 250 = 50(x + 5)
y + 250 = 50x + 250
y = 50x + 250 - 250
y = 50x

What is the probability of rolling either two identical numbers or rolling a sum of 8 using two number cubes, each labeled 1 – 6?
Answers
Answer:
5/18
Step-by-step explanation:
We have 2 things to consider here, rolling two identical numbers, or rolling a sum of 8
Rolling two identical numbers
To make this simple, think about how many possibilities there are to have two identical numbers. (1,1) (2,2) (3,3) (4,4) (5,5) (6,6). The total amount of possibilities for rolling two dice is 6*6 which is 36. That would be 6/36 which is 1/6
Rolling a sum of 8
The numbers which add up to 8 are, (2,6)(3,5)(4,4)(5,3)(6,2). With 36 total possibilities, it would be 5/36.
However, we can see, (4,4) is repeated, so we have to subtract 1/36.
Answer
1/6 + 5/36 - 1/36
6/36 + 5/36 - 1/36
10/36
5/18

He used this solution to determine how much more he needs to save.
225 90 122 35+ a
225 90 – 122 35 122 35-122 35+ a
103.55 sa
Vince says that based on the solution, he should save a maximum of $103.55.
Is Vince correct?
Vince is correct because he found the correct solution to the inequality.
Vince is correct because he should save at least $103.55.
Vince is not correct because he wrote the wrong inequality to represent the situation.
Vince is not correct because he should have interpreted the solution as having to save a minimum of $103.55.
Answers
Answer:
No, he is not correct.
Step-by-step explanation:
$103.55 is the minimum, not maximum, amount that he should save. If he adds the $103.55 to his current total, he can only by the least expensive model. However, he may want to buy more than that model.
what is 7/12 x 3 as a fraction in simplest form
Answers
Answer:
7/4
Step-by-step explanation:
use cross multiplication and you are going to end up dividing 12 by 3 to get four as your denominator
The solution to the product of the fractions is 7/4
How to evaluate the product of the fractionsFrom the question, we have the following parameters that can be used in our computation:
7/12 * 3
Express 3 as 3/1
So, we have
7/12 * 3 = 7/12 * 3/1
Evaluate the products of 7 and 3
So, we have
7/12 * 3 = 21/12
Divide 21 and 12 by 3
7/12 * 3 = 7/4
Hence, the solution is 7/4

Answers
Answer:
x = 30 degrees
Step-by-step explanation:
When two parallel lines are intersected by a transversal, the alternate corresponding angles are supplementary, meaning their degree measures add up to 180. One can apply this here by stating that the two given angles add up to 180. Then one can simplify and use inverse operations to solve for (x).
(6x - 5) + (x - 25) = 180
6x - 5 + x - 25 = 180
7x - 30 = 180

7x = 210

Which fractions have a LCD of 30? A. 3/4 1/7 16 B.2/3 1/5 1/15 C. 2/15 1/4 1/3 D. 2/3 1/5 1/6
Answers
Answer:
1/5, 1/6 and 1/15
Step-by-step explanation:
Multiples of 15 are 30, 45, 60, 75, 90. Now, when you look at the list of multiples, you can see that 30 is the smallest number that appears in each list. Therefore, the least common denominator of 1/5, 1/6, and 1/15 is 30.
The fractions with LCD of 30 are D. 2/3, 1/5 and 1/6.
What is LCD?LCD, which is the abbreviated form for Least Common Denominator, is the lowest of all the common multiples of the denominators for a set of fractions.
We need to find the set of fractions with LCD as 30.
A. 3/4, 1/7 and 1/6
The denominators are 4, 7 and 6.
30 is not a multiple of 4 as well as 7.
So this set is not the answer.
B. 2/3, 1/5 and 1/15
Denominators : 3 and 5
Multiple of 3 = 3, 6, 9, 12, 15, ......
Multiples of 5 = 5, 10, 15, ......
Multiples of 15 = 15, 30, .....
15 is the LCD.
C. 2/15, 1/4 and 1/3
Denominators = 15, 4 and 3
Again 30 is not a multiple of 4.
D. 2/3, 1/5 and 1/6
Denominators = 3, 5 and 6
Multiples of 3 = 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, .......
Multiples of 5 = 5, 10, 15, 20, 25, 30, ......
Multiples of 6 = 6, 12, 18, 24, 30, .......
LCD of three fractions = 30
Hence the set of fraction is D. 2/3, 1/5 and 1/6 has LCD equals 30.

The distance on Map A from Millersville to Augusta is in. The map scale is . Find the distance on Map B if the scale is . Round to the nearest tenth.
Answers
Answer: 4.1 inches is the distance on map B
Step-by-step explanation: Map A scale: 1 inch represents 75 mies
Multiply the given inches by the scale miles per inch distance from map A.
6.5 inches × 75 mi/inch represents 487.5 miles
Take that distance and divide by the scale miles per inch from map B
487.5miles/120 = 4.0625 inches
Rounded to nearest tenth, that is 4.1 inches.
The distance on Map B if the scale is 1 in = 120 miles is 780 miles.
What is scale factor?A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).
The basic formula to find the scale factor of a figure is expressed as,
Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.
Given that, the distance on Map A from Millersville to Augusta is 6.5 in. The map scale is 1 in = 75 miles.
Number of miles in 6.5 inches =6.5×75
= 487.5 miles
The distance on Map B if the scale is 1 in = 120 miles
Number of miles in 6.5 inches =6.5×120
= 780 miles
Therefore, the distance on Map B if the scale is 1 in = 120 miles is 780 miles.

What is the best estimation of the equation 7/8 − 6/11? Drag the numbers into the boxes. Numbers may be used once, twice, or not at all.
Answers
Answer:
1 - 1/2 = 1/2
Step-by-step explanation:
These numbers are the best estimation of the equation 7/8 - 6/11 because 7/8 is approximately 1 and 6/11 is approximately 1/2. If you subtract 1 from 1/2 you get 1/2.
The best estimation of the equation ⅞ - 6/11 is; ½
Fractions
To solve this question we need to know that sometimes when we want to get the rough estimate of some mathematical operations, it may be wise to approximate the number involved.
Now, ⅞ is closer to 1 than it is to ½ and so we will say; ⅞ ≈ 1Similarly, 6/11 is closer to ½ than it is to 1 and so we say; 6/11 ≈ ½Thus;
The operation ⅞ - 6/11 can be expressed as;
1 - ½ = ½

Answers
Answer: Mean Absolute Deviation Calculator
Instructions
This calculator computes the mean absolute deviation from a data set:
You do not need to specify whether the data is for an entire population or from a sample. Just type or paste all observed values in the box above. Values must be numeric and may be separated by commas, spaces or new-line. Press the "Submit Data" button to perform the computation. To clear the calculator, press "Reset".
What is the mean absolute deviation
The mean deviation is a measure of dispersion, A measure of by how much the values in the data set are likely to differ from their mean. The absolute value is used to avoid deviations with opposite signs cancelling each other out.
Mean absolute deviation formula
This calculator uses the following formula for calculating the mean absolute deviation:
$ MAD =\frac{1}{n} \sum_{i=1}^n |x_i-\bar{x}|$
where n is the number of observed values, x-bar is the mean of the observed values and xi are the individual values.
